Which term best describes something that merely hides an object but does not provide security?

The term that best describes something that merely hides an object without providing security is "Concealment." In security contexts, concealment refers to the act of hiding an object from view, but it does not necessarily ensure that the object is safe from theft or damage. For example, a person could conceal a valuable item in a drawer; while it may not be visible to others, there is no mechanism in place to prevent someone from easily accessing it.

Obfuscation, while related to making something unclear or difficult to understand, does not apply to hiding objects in a physical sense. Protection refers to measures that actively safeguard against loss or harm, which goes beyond mere concealment. Covering could imply placing a physical barrier over an object, but again, it doesn't inherently imply security. Thus, “Concealment” is the most appropriate term to describe a situation where something is hidden without adding a layer of security.
